"This abnormal brain activity could play an important role in the development of Alzheimer-related cognitive impairments."

The study suggests that A-beta could be the reason for Alzheimer's sufferers having a higher risk of experiencing seizures.

Dr Mucke continued: "Our results have important therapeutic implications, because the prevention and reversal of non-convulsive seizure activity has not yet been a major focus of clinical trials in Alzheimer's disease.

"Our results suggest that the suppression of this activity might prevent and possibly even reverse cognitive impairments induced by high levels of A-beta."
